Problems solved by technology

[0008] However, there are certain defects in the construction methods of the above-mentioned several floor slabs.
The first method requires a lot of cast-in-place operations, and the overall degree of assembly is low
The second method also requires certain cast-in-place operations, and at the same time, the assembly process is more complicated and the construction is more difficult.
The third method needs to use a large amount of I-beam, the overall steel consumption is relatively large, and the cost is relatively high

Embodiment 1

[0057] Such as figure 2 As shown, the floor slab of this embodiment includes a load-bearing steel truss 2 and an autoclaved aerated concrete slab 1 , and the steel truss 2 is embedded in the autoclaved aerated concrete slab 1 . The connector 5 of this embodiment adopts a connecting steel bar or a connecting steel plate, and is directly welded to both ends of the reinforcing bar truss 2 after the reinforcing bar truss 2 is manufactured.

[0058] The floor slab of this embodiment is also provided with connecting members for splicing. The connecting member in this embodiment is a mortise and tenon member, and the mortise and tenon member includes grooves 4 and flanges 3 arranged on both sides of the autoclaved aerated concrete slab 1 and matched with each other. For the present invention, all more than three hundred kinds of mortise and tenon structures in the prior art can be applied to the present invention.

[0059] This embodiment can be manufactured by using the manufactu...

Embodiment 2

[0064] The floor slab of this embodiment includes a load-bearing steel bar truss 2 and an autoclaved aerated concrete slab 1 , and the steel bar truss 2 is embedded in the autoclaved aerated concrete slab 1 .

[0065] Such as Figure 3 ~ Figure 5 As shown, the steel bar truss 2 of this embodiment can adopt various structural forms.

[0066] First of all, for floors with low bearing performance requirements (such as the floor of the first floor), multiple straight steel bars can be directly configured as steel trusses.

[0067] Secondly, for middle and low-rise residential buildings, the load-carrying performance of the floor slabs has certain requirements, and reinforced structure steel trusses 2 can be used. Such as image 3 As shown, the steel truss 2 includes longitudinally arranged upper and lower chord main reinforcements 2a, and also includes web auxiliary reinforcements 2b arranged between the upper and lower chord main reinforcements 2a. The steel bar truss 2 is des...

Abstract

The invention discloses a combined-type autoclaved aerated concrete floor slab. The combined-type autoclaved aerated concrete floor slab is formed by splicing a plurality of autoclaved aerated concrete slabs, and steel bar trusses used for bearing are buried in the autoclaved aerated concrete slabs so as to ensure that the autoclaved aerated concrete slabs meet the bearing capacity of 200 kg or above per square meter. On the premise that bearing performance is met, complete overall prefabrication of the floor slab is achieved, the manufactured floor slab is low in weight, high in strength andeasy to fabricate, a steel structure frame does not need to be arranged in advance, the construction efficiency is greatly improved, and the construction cost is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a combined autoclaved aerated concrete floor slab. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. Compared with traditional buildings, prefabricated buildings have the advantages of less on-site cast-in-place operations, a higher degree of standardization, shorter construction periods, more in line with the requirements of green buildings, and more energy-saving and environmentally friendly. In recent years, my country has attached great importance to the development of the prefabricated construction ind...
